DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figures 1 to 4As shown, a water level detection device in an embodiment of the first aspect of the utility model includes a box body 1, and the interior of the box body 1 is movably connected with a water level detection component 4 and a cleaning component 5, the water level detection component 4 includes a floating plate 406, and the cleaning component 5 includes an arc-shaped cleaning scraper 503 and a spring 505.

[0021] In the above embodiment, it should be noted that the upper end of the box body 1 is fixedly connected with the water inlet valve 2, the lower end of the box body 1 is fixedly connected with the drain valve 3, the upper end of the box body 1 is fixedly connected with the scale 401, the interior of the box body 1 is fixedly connected with switch 1 402, switch 2 403 and slide rail 404, the surface of the slide rail 404 is slidably connected with a sliding sleeve 408, one side of the sliding sleeve 408 is fixedly connected with a connecting rod 407, the upper end of the connecting rod 407 is fixedly connected with a vertical rod 405, the other end of the connecting rod 407 is fixedly connected with a floating plate 406, the upper end of the floating plate 406 is fixedly connected with a trigger rod 1 409, the lower end of the floating plate 406 is fixedly connected with a trigger rod 2 410, the switch 1 402 is arranged at the top of the inside of the box body 1, the switch 2 403 is arranged at the bottom of the inside of the box body 1, and the floating plate 406 is fixedly connected to the connecting rod 407.

[0022] The technical effect achieved by the above embodiment is: when the floating plate 406 is raised or lowered, the connecting rod 407 drives the sliding sleeve 408 to slide on the surface of the sliding rail 404, so that the movement of the floating plate 406 is more stable. When the connecting rod 407 moves, the vertical rod 405 and the scale 401 achieve the effect of water level detection. When adding water, the floating plate 406 rises to a certain height and then triggers the switch 1 402 through the trigger rod 1 409, and then the water inlet valve 2 stops adding water. As the water flow inside the box 1 is discharged, the floating plate 406 drops to a certain height and then triggers the switch 2 403 through the trigger rod 2 410, and then the water inlet valve 2 adds water again. In this way, not only the effect of detecting the water level is achieved, but also the water level inside the box 1 can always be in the best position for easy use.

[0023] Example 2

[0024] like Figure 3 and Figure 4 As shown, a water level detection device includes all the contents of Example 1. In addition, the outer wall of the floating plate 406 is fixedly connected with a slide cylinder 501, the interior of the slide cylinder 501 is slidably connected with a slide rod 502 and a limit block 504, one end of the spring 505 is fixedly connected to the limit block 504, the other end of the spring 505 is fixedly connected to the slide cylinder 501, and the slide rod 502 is fixedly connected to the arc-shaped cleaning scraper 503.

[0025] The technical effect achieved by the above embodiment is as follows: when the floating plate 406 moves, it drives the arc-shaped cleaning scraper 503 to rise and fall, and the inner wall of the box body 1 is cleaned by the arc-shaped cleaning scraper 503 to prevent foreign matter from sticking to the inner wall of the box body 1 after long-term use, and by setting the spring 505, the arc-shaped cleaning scraper 503 is always in contact with the inner wall of the box body 1 to prevent the arc-shaped cleaning scraper 503 from affecting the cleaning effect after wear, and a limit block 504 is set to prevent the slide rod 502 from detaching from the slide cylinder 501.

[0026] Working principle: water is added into the box body 1 through the water inlet valve 2, and the water is drained through the water inlet valve 2, and the water flow rate of the water inlet valve 2 is greater than the water flow rate of the water drain valve 3, the floating plate 406 floats on the water surface, and the sliding sleeve 408 is slidably connected with the sliding rail 404. When the floating plate 406 is raised or lowered, the sliding sleeve 408 is driven to move synchronously through the connecting rod 407, so that the movement of the floating plate 406 is more stable. When the connecting rod 407 moves, the water level detection effect is achieved through the vertical rod 405 and the scale 401, that is, the upper end of the vertical rod 405 corresponds to the value on the scale 401 as the value of the water level inside the box body 1. When water is added, the floating plate 406 rises, and the floating plate 406 drives the trigger rod 409 to rise. When the trigger rod 409 triggers the switch 402, the water inlet valve 2 stops adding water. As the water flow inside the box body 1 is discharged, the floating plate 406 drives the trigger rod 2 410 to descend, and when the switch 2 403 is triggered, the water inlet valve 2 adds water again, which not only achieves the effect of detecting the water level, but also enables the water level inside the box body 1 to always be in the best position for easy use; when the floating plate 406 moves, it drives the arc-shaped cleaning scraper 503 to rise and fall through the slide cylinder 501 and the slide rod 502, and the inner wall of the box body 1 is cleaned by the arc-shaped cleaning scraper 503 to prevent foreign matter from sticking to the inner wall of the box body 1 after long-term use, and the spring 505 is set to ensure that the arc-shaped cleaning scraper 503 is always in contact with the inner wall of the box body 1 to prevent the arc-shaped cleaning scraper 503 from affecting the cleaning effect after wear, and a limit block 504 is set to prevent the slide rod 502 from detaching from the slide cylinder 501.
